Description

Traffic lights remote emergency control device

Technical field

The utility model relates to signal controlling field, relates in particular to traffic lights remote emergency control device.

Background technology

Along with the fast development of China's economy, the increasing of vehicle, congested in traffic and traffic hazard problem is day by day serious.When constantly widening traffic route and building new traffic main artery, the purposes of traffic lights, electronic police, public security bayonet becomes more obvious, and we also should be suitable improves its function, utilizes new technology to make management more intelligent.

Crossroad vehicle shuttles back and forth, and pedestrian is bustling with activity, what realizes the in good order of traffic by so? what embodies the constraining force of traffic law by? what lean on is the automatic command system of traffic lights and perfect electronic police, public security bayonet system.Yet, to intersection, be only mechanical traffic control, sometimes but can hinder the current of some emergency vehicles, such as police car, fire truck, ambulance tend to because etc. red light time delay; For another example,, in the time of need to tackling illegal vehicle at crossing, be now still artificial scene fence is set, the state of field change signal lamp; For another example when signal lamp power-off or cisco unity malfunction, still need manual intervention.This is not only inefficent, but also has potential safety hazard.

Utility model content

For solving above-mentioned defect of the prior art, the utility model provides traffic lights remote emergency control device, when meeting with emergency, in traffic control center, is that cocoa is realized the emergent control to traffic lights.

For solving the problems of the technologies described above, the utility model scheme comprises: traffic lights remote emergency control device, it is characterized in that, comprise Network Interface Module, main control module, relay and power module with wireless communication function, described main control module comprises microprocessor, indicator light circuit and crystal oscillating circuit, and described indicator light circuit and crystal oscillating circuit are electrically connected to respectively on microprocessor; Described Network Interface Module carries out communication by RXD signal wire and TXD signal wire with microprocessor and is connected; Described relay is electrically connected on microprocessor by some light emitting diodes; Described power module provides working power to Network Interface Module, main control module, relay respectively.

Further, the described Network Interface Module with wireless communication function is one or both in GPRS module and WIFI module.

Preferably, described microprocessor adopts the CPU of SRC10F08 model.

The beneficial effects of the utility model are: the utility model delicate structure, with low cost, utilize microprocessor to control the break-make that light emitting diode is realized relay, thereby reach the effect of controlling traffic lights, simultaneously, utilize Network Interface Module, realized the remote control to traffic lights, make traffic only at traffic control center, just can realize the management to each road section traffic volume signal lamp of whole city.

Embodiment

Below in conjunction with accompanying drawing, concrete enforcement of the present utility model is described, should be appreciated that exemplifying embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.

As shown in Figure 1, traffic lights remote emergency control device comprises networking interface module, main control module, relay and the power module with wireless communication function, described main control module comprises microprocessor, indicator light circuit and crystal oscillating circuit, and described indicator light circuit and crystal oscillating circuit are electrically connected to respectively on microprocessor; Described relay is electrically connected on microprocessor by some light emitting diodes; Described power module provides working power to Network Interface Module, main control module, relay respectively, the described Network Interface Module with wireless communication function is selected GPRS module or WIFI module, described Network Interface Module carries out communication by RXD and TXD signal wire and main control module, and the data of control module are accessed to INTERNET network connection Master Direction Center server by network interface, realize transmitted in both directions.

Fig. 2 is concrete implementing circuit schematic diagram of the present utility model, as shown in Figure 2:

Described main control module is included as the microprocessor of SRC10F08 model, model is 7805 voltage stabilizer V22, pilot lamp LED13 and by G1, C1, the crystal oscillating circuit that C2 forms, the input end of V22 is connected after the diode V21 of company with cathode output end of power module, output terminal respectively with capacitor C 13, C15, 38 pin of C19 and microprocessor are connected, the datum line of voltage stabilizer V22 respectively with the public terminal GND of power module, capacitor C 12, C13, C15, 16 pin of the other end of C19 and microprocessor CPU are connected, 8 pin resistance in series R9 of described microprocessor and the rear ground connection of
